I think I understand the technque you are using. I would be concerned
that it could fail just by chance with large numbers of connections,
but your testing with Brandon shows that it's not much of a worry.
Feel free to commit it.

I was mindful of this in my scan.  I set --min and --max-parallelism to
768 to prevent overloading select().  I assume that's still the right
way to handle this -- if it isn't let me know.

If you are under socket pressure, NSE and especially smb-* with this
patch are very easy ways to run out of resources.
